# Credit Card helpers in PHP This is a simple package to create and validate credit card numbers. ## Installation via Composer ### In your project To use this package in your project, add it to your `composer.json` ```json "require": { "rplansky/credit-card": "dev-master" } ``` ### Global Installation This kind of installation is useful to use `ccgenerator` and `ccvalidator` commands globally on command line ```shell $ composer global require "rplansky/credit-card=*@dev" ``` ## Usage ### In code #### Validate Numbers This validator uses the [Luhn Algorithm](http://en.wikipedia.org/wiki/Luhn_algorithm) ```php $validator = new Plansky\CreditCard\Validator(); $validator->isValid('57234651187928922'); // true ``` #### Generate Random Numbers ##### Totally random ```php $generator = new Plansky\CreditCard\Generator(); $generator->single(); // 99119662018492824 ``` ##### Prefix You can generate a random number using a brand prefix. ```php $generator = new Plansky\CreditCard\Generator(); $generator->single(301); // Generates a DINERS number // 30192056094873699 ``` ##### Length Some brands have different number length. ```php $generator = new Plansky\CreditCard\Generator(); $generator->single(347, 15); // Generates an AMEX number // 3479966030620031 ``` #### Generating Lots Using same parameters of `generate` method, except for the first parameter that is the amount of numbers that you want to generate, you can generate a lot of numbers at once ```php $generator = new Plansky\CreditCard\Generator(); $generator->lot(10, 347, 15); // Generates 10 AMEX numbers // array( // 0 => '3479132843454361', // 1 => '3479587605801416', // 2 => '3479861510504500', // 3 => '3479130090772634', // 4 => '3479427298826638', // 5 => '3479894458677616', // 6 => '3479713475691154', // 7 => '3479468840371814', // 8 => '3479219690811825', // 9 => '3479326005723791' // ) ``` ### In command line #### ccgenerator You can use same parameters of `Generator::lot()` method, plus, `separator` parameter to render your output ```shell $ ccgenerator --amount=3 --prefix=347 --length=15 --separator=" " # 347544073859505 347615533406853 347845409364916 ``` #### ccvalidator You can pass numbers separated by spaces to validate more than one number at once. ```shell $ ccvalidator 347544073859505 347615533406852 347845409364916 # 347544073859505 | valid # 347615533406852 | invalid # 347845409364916 | valid ```
